But, according to the Linux SCSI sub-system documentation I have, it would
have to stand for _SCSI_ _READ_ since it is a cd drive that is designated
read-only. For generic operations on the same device, it would map to sg0
(_SCSI_ _GENERIC_) in order to gain the write perm. Apparently all of the
devices like /dev/sr0, /dev/st0, /dev/nst0x map to an sg device for generic
operations.
Although _raw_ seems to be a good logical choice.
